Getting into some of the lesser known arachnids, these guys are commonly known as short-tailed whip scorpions and they belong to the order Schizomida. They get the name "short tailed" as they have a short, stubby flagellum. I big reason why so few people know about these arachnids is because they are small. Very few species get over 1 centimeter while the majority fail to reach 5 millimeters. Schizomida and Uropygi (which I posted about yesterday) are quite closely related. There is a lot of debate going on about how to classify these in the Arachnological world. Currently there are 258 described species split into two families - Hubbardiidae and Protoschizomidae. Due to their small size, it is likely there are hundreds of more undescribed/undiscovered species out there. In the wild, these are tiny predators who mainly feed on collembolans, millipedes, isopods, cockroaches and like other arachnids, they can be cannibalistic. These are actually pretty proficient hunters. It has been noted that they can capture live prey that is 100% of their body size. It is thought that some species have evolved similar defenses as their vinegar shooting relatives.
